CXL spec rev 3.1 section 8.2.9.2.1.1 Table 8-45, General Media Event
Record has updated with following new fields and new types for Memory
Event Type and Transaction Type fields.
1. Advanced Programmable Corrected Memory Error Threshold Event Flags
2. Corrected Memory Error Count at Event
3. Memory Event Sub-Type

The format of component identifier has changed (CXL spec 3.1 section
8.2.9.2.1 Table 8-44).

Update the general media event record and general media trace event for
the above spec changes. The new fields are inserted in logical places.

Example trace log of cxl_general_media trace event,
